we went through a second round of that. and after that there have been, you know -- because we've taken our time with this, wanting to get it right and not spend millions of dollars more than we need to, we lucked into a great project manager at titan salvage who is a naval architect by training. and, so, they have been very sophisticated work on the boyancy and the sections and what is going to happen to them. it is one of the risk factors we will take into consideration in phase ii, you know, whether the bisecting work is done at mayor island so it doesn't have to go anywhere or it's done at bae, which means those pieces would then have to be towed back out. it adds an additional piece of risk. so, you know, coming up with the final recommendation on this really is a weighing of risk/reward. the cheapest alternatives, and they're significantly cheaper, you know, appear to be the riskiest, the most expensive, the least risk.
